Abstract

An OLED device is disclosed. The device includes a substrate defined to have a first active area and a dummy area. First electrodes are formed on the substrate, and a first bank pattern is formed to overlap with edges of each first electrode and to expose a part of an upper surface of each first electrode. A second bank pattern is formed on the first bank pattern within the first active area, and a third bank pattern is formed on the first bank pattern within the dummy area in the same layer as the second bank pattern. The second bank pattern is formed to have a larger width than that of the third bank pattern. As such, an organic emission layer can be evenly formed in the active area.

Dependent claims

An organic light emitting display device comprising:

a substrate defined to have a first active area and a dummy area;
first electrodes disposed on the substrate;
a first bank pattern disposed to overlap with edges of each first electrode and expose a part of an upper surface of each first electrode;
a second bank pattern disposed on the first bank pattern within the first active area;
a third bank pattern disposed on the first bank pattern within the dummy area in the same layer as the second bank pattern;
a first organic emission layer disposed on the exposed upper surface of the first electrode within the first active area;
a second organic emission layer disposed on the exposed surfaces of the first electrode within the dummy area, wherein the second organic emission layer covers a larger area of the first electrode than the first organic emission layer;
and
a second electrode disposed on the substrate including the second and third bank patterns and the first and second organic emission layers.
